Algebraic deformation for (S)PDEs
Algebraic deformation for (S)PDEs
We introduce a new algebraic framework based on the deformation of pre-Lie products. This allows us to provide a new construction of the algebraic objects at play in regularity structures in the works by Bruned, Hairer and Zambotti (2019) and by Bruned and Schratz (2022) for deriving a general scheme …
